Temperature sender fault?

[BavSat]

Hi..

I have 2006 T220 connect ( I think its a 1.9 tdci)

Anyways...

Whilst driving at regular speed I often experience lack of power..

This is followed by the temperature gague increasing to the full red, and then the engine cuts out.

5 mins later all is fine..

I have checked all electrical connections for breaks etc.. but they are fine.

The engine does not feel very hot at all!, so I do not think its the engine over heating... However, the radiator remains cold...

Coolant, oil and all is in order..

if I was to take a stab at the problem, its a sensor that monitors the intercooler oil temp... but hey, I fit satellites, not car parts..

Has anyone else had simmilar problems or can anyone help?

Thanks

Geoff

Hmmmm.

Even though you say the engine doesn't feel exceptionally warm, I would suspect your thermostat is bad, b/c your radiator is cool. You can check the thermostat by removing it and boiling it to make sure it opens at the correct temp, but I usually just replace it b/c they aren't real expensive.

I thought that too!

However, the Temp gague goes from Middle to "RED" as if it were the Petrol gague on a full tank! Its that fast.

Haven't had this problem on a vehicle in a long, long time. But if your coolant blend is not up to snuff, it can cause this problem

Ice forms in the radiator, or in the hose near the thermostat and becomes a plug. This causes overheating.

Check your cooland blend and make sure it can handle the temps you guys have been getting.

I'm sorry. In other words, have you been topping off your coolant level with water only?
